Question
The number of present boys to girls is in the ratio 2:1.
If 15 girls are absent and they form 25% of the total class, and no boy is absent, then find the number of boys in the class.Solution
Total number of students = 15/0.25 = 60
Number of students who are present = 60 – 15 = 45
Therefore, number of boys in the class = 45 × 2/3 = 30
